On Friday, episode 13 drops, which gets into the Fang Clan story arc that see's Kenshiro and Rei fight together for the first time against a major adversary. He kidnaps Airi, Rei's sister, and eventually captures Mamiya as well, thinking she is Kenshiro's wife.
I suspect the scene will occur over both episode 13 and 14 given the length of the story, but basically Airi and Mamiya wind up bound and gagged at cliffside to watch Ken and Rei duke it out. I've added a few panels from the manga so you can get a sense of the scene. It also occurs of course in the original animated series, but the manga is better. As the new show is more manga-oriented, I expect this scene will be upgraded in animation as well soon.
